Honestly I couldn't tell you cuz I don't know what the port looks like new..now i'm curious.

that thing is definatly running gasketless and the exhaust port looks like its got a bobble in it. but the intake looks to have two casting lines it it unless its just camera makn it look the casting lines are still there. but i bet the intake has been hogged out because it looks to round i doubt its round like that from the factory

I'll take some pics tonight, but since you mentioned it....sure looks like red RTV for the gasket.

 

[Motodeficient]

Where did you pick the saw up from?

 

[gmcman]

Was a CL find. Looks like there is a small layer of RTV under the gasket on the exhaust pic. Unless it's still dirty at the base.

 

[gmcman]

Here's some better pics of the intake/exhaust. Looks like the intake has seen some machining....not sure about the exhaust.

 

[gmcman]

So is this a factory intake port or has it been ported?

 

[parrisw]

To me it looks like it has been ported.

How much is this going to alter the power curve of this motor? Granted I won't know until it's back together but is this more for top-end power only, higher RPM's, will it ruin the bottom end power not that it's used much.

Couldn't really tell you, depends on what they did. Squish has been reduced by removing the cyl gasket, so that will increase compression, giving more torque.

That is one odd shaped intake port. Check out the groove in the top of it.

Good eye brad, that definitely wierd??

The exhaust has definately been ground on. No doubt about it. I would absolutely be pulling the jug to check things out, and you can properly decarbon it while you're in there. Your compression is good, so the exhuast hasn't been raised too high. I'd just want a better idea of what's been done in there. It might be a real runner.

Ya, I agree, don't know why they would touch the top of the intake though?? I guess they didn't know what they were doing.

Or maybe we don't know what we're doing and it's an old secret trick, lol!

LOL ya I've never claimed to really know what I'm doing, just a beginner at this stuff.

 

[blsnelling]

I've heard of weird grooves in the exhaust, but not the intake.

 

[gmcman]

Allright you talked me into it ....i'll pull the jug and take some pics. I have a set of gaskets lying around anyway.

You could do with a little less sealer than what they used previously.
Hate to think what's hanging out here is hanging on the inside.

Another good reason to pull that jug and clean things up.
